Assumptions confuse investigations. (leading the investigation in the wrong direction)
Suppose there is a private practice called "Takahashi Clinic".Suppose there is also a general hospital called "Takahashi Hospital".
An investigator heard from an eyewitness to the incident that the suspect had been to Takahashi Clinic.
However, the investigator is pulled by the word "hospital", which is a common expression, and unconsciously believes that the information he was originally asking was "Takahashi Clinic" but "Takahashi Hospital", and reports to the person in charge of the investigation. Sometimes, I will report that "the suspect was going to 'Takahashi Hospital'."Naturally, the person in charge of the investigation conducts various investigations on "Takahashi Hospital", but of course no information leading to the suspect comes out.
It's like a quiz, but it would be nice if the person in charge of the investigation noticed that it was a "clinic" instead of a "hospital", but if the person in charge and the investigators didn't notice, there would be no results.
Also, if you expand the investigation target and investigate "clinics", you will get results, but you will waste time and personnel.
It's a simple example, but mere verbal assumptions can lead an investigation in the wrong direction.
If this assumption is the time and place of occurrence of the incident related to the criminal facts, this incident may never be resolved.You can see how difficult it is to convey information accurately, even with just one word.Therefore, investigators will conduct investigations such as interviews with as many people as possible.Check with multiple eyes and ears and try not to misjudge the facts.
The contents of the investigation are always documented in documents called investigative reports and statement records.
Of course, it goes without saying that the information acquired by eyes and ears is converted into text information correctly.
The above example is a human error made by humans, but in order to eliminate that error, in this example, by psychologically studying "assuming", you may be able to get a hint of how to prevent it. .
